Convering lens made of ice

    Converging lens made of ice

    Would it be possible to start a fire by shaping a piece of ice ? That's the question.

    I'm thinking that yes it would be possible if you shaped the ice in the form of a converging lens. Even though the lens is made of ice, the sun rays would not burn through it since the rays would converge on a point behind the lens and not in the lens itself.

    I just want to know if my reasoning holds correct. Thanks

    The ability of a lens to focus light is basic optics. There's no reason why it wouldn't be possible with an ice lens.
